WINDOW SASH AND FRAME.

SPECIFICATION forming part of Letters Patent No. 321,603, dated July '7, 1885.

Application filed November i5, 1884. (No model.)

To all whom, it may concern:

Beit known that I, GEORGE W. HENRY, of Elizabeth, Union county, and State of New Jersey, have invented a new and Improved Window Sash and Frame, of which the following is a full, clear, and exact description.

r)This invention consists of a window frame and sash constructed in such manner, with inclined or wedging surfaces,that practically airtight joints will be formed at all points between the sash and frame when the sash is lowered to closed position, as will be hereinafter described and claimed.

Reference is to be made to the accompanying drawings,forming part of this specication, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation of my invention, taken on the line .fo v of Fig. 3. Fig. 2 is a transverse sectional elevation taken on theline y u of Fig. l; and Fig. 3 is a sectional plan view taken on the line e z of Fig. l.

a a represent the side pieces of the windowfranie, b represents the window-sill, and c the lintel.

B represents the upper and G the lower window-sash, held in place in the window-frame by the stop strips or beads d d and d d and the division-strips e e, (shown clearly in Fi g. 3.)

Thelower strip, f, of the upper sash, B, is thicker horizontally than theupper strip, f', and the side strips, g g', of the said sash B are beveled or inclined at their outer surfaces, being made thickest at their lower ends, as shown clearly in Fig. 2, and the said inclined outer surfaces of the strips g g run against the stop strips or beads el d', the inner edges of which are inclined, being made widest at the top, as shown in Fig. 2, so that these inclinations cause the sash B to be wedged firmly against the divisionstrips e when the sash B is closed.

The strips g g of the said upper sash, B, are also beveled or inclined at their edges, being made widest at their lower ends, as shown in dotted lines in Fig. l, and these outer-inclined edges run against the wedgepieees k h, secured to the side pieces, a a, of the window-frame, so. that sash B when closed will wedge itself in the frame and form perfectly-tight joints all along its side edges with the said wedge-pieces h.

The upper strip, t', of the lower sash, C, is thicker than the lower strip, fi', and the side pieces, k 7c', are inclined or beveled at their front surfaces and rnn against the inner inclined edges of the stop strips or beads d d, which are made widest at their lower ends, so that when the sash C is closed it will be held with a wedging action against the divisionstrips e e, thus forming perfeetly-tight lioints. The strips 1c k are also inclined at their edges, as shown clearly in Fig. l, and these inclined edges run against the wedge-pieces Z Z, so that these oppositely-inclined surfaces wedge the lower sash, C, in the frame when closed down, thus making the joints perfectly tight in the frame in all directions.

The cross-pieces m m, secured, respectively, upon the window-sill b and to the lintel c, have beveled inner surfaces to effect wedging action with the strips f t" of the upper and lower sashes when closed, to cause tight joints to be formed at the top and bottom of the window, and the strip i of the lower sash, C, is cut away, as shown at i3 i3, Fig. 3, to form the tongue'i'?, the ends of which run against the adjacent edges of the division-strips e, which edges of the said strips are inclined, the strips being made widest at the bottom, so that the ends of the tongue ft2 when the sash C is closed will wedgefbetween the division-strip e and form tight `joints with the said divisionstrips.

In this manner it will be seen that the sashes B C are heldagainst inclined or wedging surfaces in all directions, front,hack, and edgewise, so that when they are closed no air, dust, or snow can enter the window, andthere will be no rattling of the sash in the window-frame.

It will be understood that I may apply my invention to various other uses-such, for eX- ample, as solid sliding hatehways or doors, and t0 other frames placed in openings and adapted to slide, and embodying the same principle of construction-and hence I do not confine myself to the'single application to windows.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A window-sash constructed with inclined IOC side edges and inclined front or outer surfaces, 3. The inclined division-strips e, in combinaithe frame being formed with oppositely-intion With the sash C, formed with the lip 2, clined surfaces, substantially as and for the substantially as described.

purposes set forth. GEORGE W. HENRY. 5 2. A Window-sash made thicker and wider Witnesses:
